Title: Fault diagnostic device for motor controller
Inventor: OBARA MASAKI
IPC: H02P29/00
Filed: 1988-05-18
Abstract: PURPOSE:To discriminate the cause of faults by estimating the disturbance torque of a motor in different aspects respectively based on the voltage, current and speed signals and by estimating the faulted region from each estimate. CONSTITUTION:A speed regulator(ASR) 7 outputs a current command I* in accordance with the deviation between a speed actual value N and a speed command N*. A current regulator(ACR) gives a voltage command V* in accordance with the deviation between a current actual value l and a current command I* to a striking pulse regulator 9. On the other hand, a state observer 10 estimates a plurality of disturbance torque mutually different taud1, taud2, taud3 based on the current actual value I, a speed actual value N and a voltage command V*. A fault diagnoser 11 detects the deviation between each disturbance torque taud1-taud3 and discriminates the fault state in accordance with these deviated states.

Filed: 1990-05-08
Abstract: PURPOSE:To uniform the direction of a current which flows to nonlinear resistance elements, to prolong the life of the resistance elements, and to suppress the generation of picture element defect by inverting the select potential of a scanning signal at intervals of two scanning lines and driving the elements. CONSTITUTION:Many driving electrodes 31a, 31b... are selected in couples sequentially from above and data is charged by counter electrodes 32 in selection periods.

Title: Accumulator internal combustion engine
Inventor: TANAKA TAMON
IPC: F02D41/38
Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To precisely grasp the pressure within an accumulator and improve the exhaust gas characteristic by detecting the pressure within the accumulator within a specified period from the end of fuel injection of an injection valve to the start of injection in the fuel injection valve of the next cylinder after the lapse of a prescribed time from it, and drive-controlling the injection valve on the basis of the detected pressure. SOLUTION: During the operation of an engine, an ECU 5 detects the engine speed on the basis of the output of a crank angle sensor 21, judges exhaust mode or not, and calculates an average rail pressure Pc from the output of a rail pressure sensor 15 for detecting the pressure of a common rail (accumulator) 3 when the exhaust mode is not selected. The current-carrying time to an injector control valve 4a is calculated from the resulting average rail pressure Pc and a target injection quantity based on the engine operating state to perform a fuel injection. On the other hand, when the exhaust mode is selected, only the rail pressure Pcr in 90 deg.-BTDC is measured, and the current-carrying time to the injector control valve 4a is calculated from this value and the intended injection quantity to perform the fuel injection.

Title: Scavenging equipment for two-cycle internal combustion engine
Inventor: TAKAHASHI HISASHI
IPC: F02B25/04
Filed: 1979-09-21
Abstract: PURPOSE: To greatly reduce fuel consumption by securing to an external wall of a cylinder liner an outer race through which many scavenging apertures open, and inserting between the outer race and the external wall of the cylinder liner a valve plate through which many scavenging pinholes open.  
     CONSTITUTION: Upper and lower scavenging through holes 2, 3 are made on the lower side of a cylinder liner 1 and a scavenging self-control valve 4 is attached so as to cover the line of the upper scavenging through-holes 2. The scavenging self- control valve 4 consists of an outer race 5 through which many elliptical pinholes 5a open arbitrarily, and a valve plate 6 which is inserted between the outer race 5 and the cylinder liner 1. Many elliptical apertures 6a are drilled arbitrarily in the valve plate 6. While a high pressure exhausting is executed, the valve plate 6 is elastically stuck onto the outer race 5 due to a pressure difference between the inside and outside of the valve plate 6, preventing a high pressure gas in a cylinder from flowing into a scavenging room. When a piston 12 is lowered to reduce a gas pressure in the cylinder, the valve plate 6 is detached from the outer race 5 and allows an inflow for beginning scavenging.
